Base64
Encode or decode Base64 text.
Frequently asked questions
What is Base64 encoding?
Base64 represents binary data using 64 printable ASCII characters, so it can travel safely through systems that only handle text — for example email attachments and data URLs.
Is Base64 encryption?
No. Base64 is reversible encoding, not encryption. Anyone can decode it. Never use it to protect secrets.
